ABB 9T58K Series Encapsulated Control Power Transformer

The ABB 9T58K Series is a family of Type IP encapsulated control power transformers built on open-core-and-coil construction for industrial and light-duty loads, HVAC applications, signal and alarm systems, industrial control panels, lighting circuits, and general circuit isolation. The 9T58K Series is available across primary/secondary voltage configurations to match a range of control power applications, including 240x480V Primary to 120/240V Secondary and 575V Primary to 230-115/95V Secondary, giving specifiers a single dependable platform to cover multiple voltage requirements without switching to a different transformer family. This series offers an economical alternative to high in-rush/machine tool transformers, and optional fuse block adapter kits add further input and output flexibility for a wide range of control power circuits.

Key Features

  • Encapsulated Open Core & Coil Construction: a sealed, general-purpose design built for durability in industrial and control panel environments.
  • Type IP Control Power Transformer: suited for industrial and light-duty loads, HVAC applications, signal and alarm systems, and lighting circuits.
  • Voltage Configuration Range: available in 240x480V Primary - 120/240V Secondary and 575V Primary - 230-115/95V Secondary options, providing flexible circuit isolation across the 9T58K Series.
  • KVA Ratings: available in ratings such as 2KVA to match load and application requirements.
  • Fuse Block Adapter Kits: optional kits enable added input and output flexibility.
  • Economical Design: a cost-effective alternative to high in-rush/machine tool transformers for general control power needs.

ABB 9T58K2814 – Frequently Asked Questions

1) What primary and secondary voltage combinations does the ABB 9T58K control power transformer come in?
Two voltage configurations are offered in the 9T58K Series. Model 9T58K2814 is the common industrial control build: 240x480V primary to 120/240V secondary, so it can be wired for either 240 or 480 volt incoming power and put out 120V control power (or 240V with the secondary in series). Model 9T58K0074 is a 575V primary unit with a 230-115/95V secondary, for plants running 575V distribution. Pick by what is actually feeding the panel, since the 575V unit cannot be reconnected for 480V service.
2) What is the equivalent to an ABB 9T58K control power transformer from Square D?
The closest Square D counterpart is the Type T industrial control transformer, 9070T series. Both are industrial control power transformers intended for control panels and similar control circuits. The ABB 9T58K is a Type IP encapsulated open-core-and-coil design offered in configurations such as 240x480V primary to 120/240V secondary and 575V primary to 230-115/95V secondary, so when cross-referencing to a 9070T unit, match the primary and secondary voltage combination and the KVA rating your control circuit requires.
3) Does the ABB 9T58K transformer come with fuse blocks, or do I have to order those separately?
Fuse blocks are not part of the transformer. ABB offers optional fuse block adapter kits for the 9T58K Series that add input and output flexibility, and those are a separate line item on your order. If your panel drawing calls for primary and secondary fusing, budget for the kit plus the fuses themselves.
4) Can I get the 9T58K to output 240V instead of 120V for control power?
On the 240x480 to 120/240V unit, yes. The secondary is a dual 120V arrangement, so the two halves can be connected in series for 240V output or in parallel for 120V at higher current. The 575V model is different: its secondary is a 230-115/95V arrangement, so it gives 230V, 115V or a 95V tap rather than a 120/240 setup.
5) I need a control transformer for a government job with Buy American requirements. Is the ABB 9T58K acceptable?
Buy American Act and ARRA status on the 9T58K is a manufacturer determination, and ABB lists country of origin as unknown on this series. For a federally funded project where domestic content has to be documented, get written confirmation from ABB for the specific model number before you submit it, because a UKN origin code will not survive a submittal review on its own.
6) What does encapsulated open core and coil construction mean for a control transformer in a dusty plant environment?
The 9T58K windings are sealed in an encapsulating compound rather than left open to air. That resin fill keeps dust, moisture and vibration off the coil, which is why this family is specified for industrial and control panel environments. It is still a panel-mount device, not a weatherproof enclosure, so it belongs inside an enclosure rated for the location.
7) Can I use the ABB 9T58K to isolate a control circuit from the line side?
Circuit isolation is one of the named applications for the 9T58K Series. Because the primary and secondary windings are separate, it breaks the direct connection between your incoming distribution voltage and the control circuit, which is standard practice for grounding one leg of a 120V control system. The same unit also covers HVAC controls, signal and alarm circuits and lighting loads.
8) Is the 9T58K transformer sold individually or in a multi-pack?
Each 9T58K transformer ships as a single unit, packaged 1 EA. Order one per panel, and add the fuse block adapter kit separately if your design requires primary or secondary fusing.
